FLOAT-VALVE.

To all whom it may concern:

Be it known that I, Fnnimncrr GEORG WANenLIN, engineer, a subject of theKing of Saxony, and resident of 73 Holbeinstrasse, Dresden, Kingdom ofSaxony, German Empire, have invented a new and useful Improvement inFloat-Valves, of which the following is a specification.

rlhis invention relates to valve-casings such as are commonly employedfor water supply pipes in water tanks from which water is siphoned forflushing closets.

One of the objects of the invention is to provide novel means by whichthe position of the valve with relation to its lever is fixed andinsured.

A further object is to arrange outlet-channels between the valve and itsinclosing casing in such a manner that the water issuing from suchoutlet-channels passes clear of the valve-lever. For these purposes thevalve is of square shaped section and provided with four guiding edges,whereas the lever for operating the valve is of roof-like or triangularsection. Said lever is passed along 1n a curve below the valve in such amanner that the lower ends or openings of the outlet-channels formedbetween the inner wall of the valve-casing and the outer surface of thevalve are situated entirely free, thus the issuing flush-water may bedischarged without splashing and without coming in contact with thevalve-lever.

A further object of the present invention is to cast the valve casing asa whole in the shape of a pipe and to manufacture the valve in asimilarly easy way by removing parts of its outer surface to form thefour supply-passages situated between the valve and inner wall of thevalve-casing. Thus there are nowhere sharp edges within the valve-casingand on the valve itself so that any splashing of the flush -water isprevented.

A convenient and desirable construction in which my invention may beembodied is Specification of Letters Patent.

providedv with a valve-casing forming the object vof the presentinvention.

a is a cross-bar provided within the top part of the flushtank or vesselz' and receiv ing from below a valve-casing b, the bottom flange ofwhich is provided with elongated parts c for fastening the valve-casingo to the cross-bar a within the flush-tank z' and also with a projectioncarrying on its lower surface the eyes CZ between which the valvelever eis inserted and supported by a pin in a well known manner.

f is the valve-seat adapted to be screwed into a horizontal partitionprovided within the valve-casing Z), and g the valve loosely insertedfrom below into the casing Z) and being of the sectional shape shown inFig. 3. ln consequence of the square shape of the valve g it is onlyguided by means of its four narrow edges arranged diagonally oppositeeach other in pairs whereas the re vmaining outer surface of the valveis formed in such a manner that between each of the two narrow guidingedges a smooth broad surface is obtained which together with the innerwall of the casing ZJ provides for a segment-shaped outlet-channelthrough which the flush water will issue.

Into the top recessed end of the valve g there is inserted a plug 71, ofindia rubber or the like, which on lifting the valve g will cont-actwith or close up against the ringshaped valve-seat The bottom part ofthe valve g is in the manner of a screw-head provided with a broad notchg for receiving a tongue-like nose 72 projecting from the top rim of thevalve-lever e, being of triangular o-r roof-like shape, as clearly seenby Fig. 4.

The flush-tank provided with the valvecasing forming the object of thepresent invention is shown in Fig. 5. In the center of the tank orvessel z' but in rear of its longitudinal axis is situated thebell-shaped cover Z suspended in a well known manner from a lever m andsurrounding the iuslrpipe n the passage-section of which graduallyinlll@ cover Z and the valve-casing b, and the third one lying towardthe left hand side on the drawing serves as a chamber for retaining aconsiderable portion of any dirt or undesired foreign matter containedin the ushwater. For this purpose the low partition wall g d'oes notreach from the front wall to the back wall of the flush-tank z', butleaves an opening near one of the walls for allowing the flush-watertogether with its undesired foreign matter to ent-er the smallcompartment.

The valve-lever e carries at one end the bell or float r and at theother end a weight s. The compartment on the right-hand side formed bymeans of the partition-wall p for receiving the float. 1" is connectedby means of a Siphon-pipe t in a well known manner with the flush-pipen.

The operation of the valve-casing and the flush-tank described above isas follows: When the compartments are filled by the water issuing fromthe valve-casing Z) said water will rise in the middle and left handside compartments and overflow the partition p thus filling also theright hand compartment. By raising the level within such compartment thefloat 1 is raised and a pull is exercised by the weight s on thelefthand end of the lever e, whereby the valve g together with its plugL is pressed against the valve-seat f by the nose or projection and thepassage of water through the valve-casing b is stopped. Vhen it isdesired to start the siphon-action the left hand end of the lever m ismoved in a downward direction, the bell shaped cover Z is moved in anupward direction and the water contained within the right handcompartment is removed by sucking-action within the siphonpipe t, sothat the level in said compartment is lowered and the float 11 will movein a downward direction. In this manner, a pull is exercised on theright-hand end of the lever e, its nose or projection 7c moving awayfrom the valve g which thus is, by means of the water pressure existingabove it and within the upper part of the valve-casing forced off thevalve-seat, f so that the flushwater can enter the lower part of thevalvecasing and pass through and issue from the same in a downwarddirection. The lever c is provided with a curved part which passes belowthe valve g and with a U-shaped part, to permit the downward movement ofthe right hand part of the valve-lever e wit-hout interruption by theupper edge of the partition p. Vhen the plug h of the valve g has leftits seat, the lower openings of the four segment-shaped outlet-channelswithin the valve-casing are entirely opened and the water does notescape from the valve-casing b in a full jet but in four-single thinjets. By curving the lever the water is enabled to emanate clear of thelever and the latter will in no way be in contact with the water-jet, sothat a splashing of the flushwater is entirely prevented.

What I claim is:

l. In a valve casing for flush tanks, the combination with a valve ofsquare section provided with guiding edges and a broad surface betweenedges for forming thin water jets, ofra valve lever of triangularsection and means for insuring and maintaining the position of the valvewith relation to the valve lever, substantially as described andspecified.

2. In a valve-casing for flush tanks the combination with a valve ofsquare section and provided with four guiding edges and a broad surfacebetween successive edges for forming four t-hin water jets, of avalvelever of triangular section and ofmeans for insuring andmaintaining the position of the valve with relation to the valve-lever,substantially as described and specified.

3. In a valve casing for flush tanks, the combination with a valve ofsquare section, provided with four guiding edges and a broad surfacebetween successive edges for forming four thin water jets, the saidvalve having a notch in its bottom end, of a valve controlling lever oftriangular section, the said valve controlling lever being provided witha projection in position to enter the notch at the bottom end of thevalve, substantially as described and specified.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two witnesses, this thirteenth day of November1909.
